He must contact his baptismal parish and get a new baptismal certificate which will show all sacraments received. When a person is confirmed, married, ordained, or professes religious vows that information is reported to the baptismal parish and entered on the permanent record. Periodically all parish records are sent to the diocese for microfilming so the diocese has archival sacramental records. This is covered in canon law, and the particular law of each diocese. The pastor is directly responsible for recording sacramental information. If a baptized Christian enters into full communion with the Catholic Church through profession of faith, confirmation and first communion, that data is recorded in the parish baptismal record, along with the information about the date and place of his baptism, and marriage if any. The baptismal record may not be changed, but facts such as legal name change, adoption etc. may be entered and the court documents appended to the record (with a notation of what information is to be placed on a new copy of the baptismal certificate). Annulments are entered, also dispensations if required for marriage in that section as well.
The person must present a new, recent baptismal certificate showing all sacraments received if he is being confirmed, married or ordained outside his baptismal parish where he is known.
